"My elderly mother is partially blind and disabled. On November 1, 2021 her washing machine broke leaking water in her home. In desperation she called rotor rooter. Roto rooter came out, stopped the leak, and put dryers in and left. They returned a few days later to remove the dryers. The technician quoted my mother a cost of about $3000.00. My mother signed a contract but could not see what she was signing. After Roto rooter Reno removed the dryers they sent a bill to my mother for $9000.00. The contract she signed stated Roto rooter would remove walls, roofing, insulation, baseboard, tile etc. Roto rooter didn’t do any of those things. Roto rooter is price gauging and took advantage of an elderly disabled woman. Roto rooter technicians were in the home no more than 3 hours total. First my mother did not have capacity to enter into a contract as she couldn’t see what she was signing. 2 Roto rooters technicians told her the cost would be about $3000.00. 3 Roto rooter did not do the work in the contract. I believe Roto rooter is commuting elder abuse and fraud."

Job done in an hour. Is $1k to expensive? When 1000's are experiencing the same issue? No you do what you need to do to come back online. I was happy with their business.

"I would absolutely not recommend Eco Electric Company. It took them nearly a month just to install a furnace — a job that should’ve been done in a few days. Their troubleshooting skills are seriously lacking, and I paid the price for it. Initially, they charged me $4,500 just to “level” the old furnace, claiming that would fix the issue. It didn’t. After wasting all that time and money, they came back and told me the furnace actually needed to be replaced — and asked for another $5,500 to do it. In total, I ended up paying $10,000 just to replace one furnace, all because they couldn’t properly diagnose the problem from the start. Completely unprofessional and frustrating experience. Stay far away."

"This was by far the absolute worst experience that I have ever had with any company. The plumber came out for a shower that was not draining. I am on septic and let them know that my septic was just pumped in July. However they wanted to check anyways. After checking under the baffle inspection, I was advised by the plumber that my septic tanks were full and needed to be pumped. I contacted a septic company they came out first thing the next morning and checked my septic tanks, they were not full and ironically enough was able to pull out a huge clog of toilet paper from the baffle. He advised this is something that the plumbers do but since we just had one out the day before and they did told us the wrong information he would happily fix the problem for us. My husband called Riley Cahill (the manger) the next day to try to talk to him about the situation and try to find out why we were charged so much since there was not an itemized receipt. Riley proceeded to get very defense and angry and HUNG UP on my husband. He then called back left a message that saying he will check with his plumbers on Monday and get back to us. Monday morning I called Riley Cahill to have a conversation of what went wrong and how we will remedy the situation. He proceeded to once again get very upset, raise his voice and was insanely disrespectful (telling me to be quiet and stop talking). Then hung up on me as well. After that he called back to tell me I was wrong, and hung up on me again. I told him during the conversation that I was going to warn anyone I could not to use this company through reviews, DO NOT USE THIS COMPANY!!!!"

FAQs for plumbing installation for a remodel or addition projects in Kirkland, WA

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
